Does a Lua Table / Array Beautifier exist?

Question

Considering all the json, xml formatters\/beautifies out there, I've been unable to find one for Lua tables\/arrays ?

function dump(o)
    if type(o) == 'table' then
        local s = '{ '
        for k,v in pairs(o) do
            if type(k) ~= 'number' then 
                k = '"'..k..'"' 
            end
            s = s .. '['..k..'] = ' .. dump(v) .. ','
        end
        return s .. '} '
    else
        return tostring(o)
    end
end

An example of such processing, you can correct the little things yourself:

function dump(o,level)
    level = level or 1
    if type(o) == 'table' then
        local s = {}
        s[1] = '{ '
        for k,v in pairs(o) do
            if type(k) ~= 'number' then 
                k = '"'..k..'"' 
            end
            s[#s+1] = string.rep('\t',level).. '['..k..'] = ' .. dump(v, level+1) .. ','
        end
        s[#s+1] = string.rep('\t',level) .. '} '
        return table.concat(s , "\n")
    else
        return tostring(o or 'nil')
    end
end
local t = {[1] = nil,[2] = { ["attr"] = { [1] = code,[2] = remaining,[3] = resetdate,["remaining"] = 990,["resetdate"] = 1638614242,["code"] = 200,} ,["tag"] = success,} ,[3] = nil,["attr"] = { } ,["tag"] = prowl,}

print (dump(t))
